1. Does the consol need to be removed with the gauges? If so where did you start? No you do not remove the console but you remove the gauges, see this pic.

2. Does the stock grip "Pull" off? YES

3. Does this install require any work underneath the vehicle work? Yes for the shifter the first time after that, you but on the upper 1/2 you want, for the ball or T-Handle, Or but on the top for the OEM handle,

4. Would you suggest Lock-tight so the ball or t-handle will not move while in a hard shift, or strip the threads? The T-Handle comes with some Lock-tight for the inner threads ( it has universal threads and all size threads ) but for the ball i have 8500 Mi on it with no moving of the ball.
BTW - looks bad ass.
